1. Introducció
This manual provides essential information for the safe and efficient installation, operation, and maintenance of the Schneider RM22TR31 3 Phase Voltage Control Relay. Please read this manual thoroughly before using the device.
The RM22TR31 is designed to monitor 3-phase supply voltage, detecting phase sequence, phase failure, undervoltage, i overvoltage conditions. It is suitable for various industrial and commercial applications requiring reliable voltagSeguiment.
2. Informació de seguretat
ADVERTIMENT:
- Desconnecteu sempre l'alimentació abans de la instal·lació, el manteniment o la resolució de problemes.
- La instal·lació i el manteniment només els ha de dur a terme personal qualificat.
- Assegureu-vos de posar a terra correctament per evitar descàrregues elèctriques.
- No feu servir el dispositiu si està danyat.
- Compliu tots els codis elèctrics locals i nacionals.
El no seguir aquestes instruccions pot provocar la mort, lesions greus o danys a l'equip.

The RM22TR31 relay features a compact design for DIN rail mounting. Key components include:
- Terminals d'entrada: For connecting the 3-phase supply voltage (A1, A2, M, E1, E2, E3).
- Relés de sortida: Two changeover (C/O) contacts for control circuits.
- Dials d'ajust: For setting voltage thresholds and time delays.
- Indicadors LED: To display operational status and fault conditions.
4. Configuració i instal·lació
4.1 Muntatge
The RM22TR31 is designed for mounting on a 35mm DIN rail. Ensure adequate ventilation around the device.
- Hook the top edge of the relay onto the DIN rail.
- Premeu fermament la vora inferior fins que encaixi al seu lloc.
- Verify that the relay is securely fastened.
4.2 Cablejat
Refer to the wiring diagram provided with the product for specific connection details. Ensure all connections are tight and secure.
- Connect the 3-phase supply voltage (L1, L2, L3) to the corresponding input terminals (e.g., A1, A2, M or E1, E2, E3 depending on configuration).
- Connect the control circuit to the output relay contacts (12, 17, 21, 22, 24).
- Use appropriate wire gauges for the current and voltage qualificacions.
5. Instruccions de funcionament
5.1 Engegada inicial
After installation and wiring are complete, apply power to the system. The relay will perform a self-test. Observe the LED indicators for proper operation.
5.2 Configuració de paràmetres
The RM22TR31 allows adjustment of several parameters using the front-panel dials:
- Undervoltage Llindar: Set the minimum acceptable voltage nivell.
- Overvoltage Llindar: Set the maximum acceptable voltage nivell.
- Time Delay (On/Off): Adjust the delay (0.1-30 seconds) before the relay trips or resets after a voltage anomaly is detected. This prevents nuisance tripping from momentary fluctuations.
Use a small screwdriver to carefully adjust the dials to the desired settings according to your application requirements.
6. Manteniment
The Schneider RM22TR31 is designed for minimal maintenance. However, periodic checks are recommended to ensure optimal performance and longevity.
- Inspecció visual: Inspeccioneu regularment el relé per detectar qualsevol signe de danys físics, decoloració o connexions soltes.
- Estanquitat del terminal: Periodically check and re-tighten terminal screws to ensure good electrical contact.
- Condicions ambientals: Ensure the operating environment remains within the specified temperature and humidity ranges. Keep the device free from dust and moisture.
No user-serviceable parts inside. Do not attempt to open or repair the unit.
7. Solució De Problemes
This section provides guidance for common issues. For problems not listed here, contact Schneider Electric technical support.
| Problema | Causa possible | Solució |
|---|---|---|
| Relay not powering on | Sense entrada voltage; Incorrect wiring; Blown fuse in supply line. | Verifiqueu el volum d'entradatage at terminals; Check wiring against diagram; Inspect and replace fuses if necessary. |
| Relay trips unexpectedly | Voltage fluctuations; Incorrect threshold settings; External interference. | Adjust time delay to filter momentary fluctuations; Re-evaluate and adjust voltage thresholds; Check for sources of electrical noise. |
| Relay does not trip on fault | Incorrect threshold settings; Fault condition not severe enough; Internal malfunction. | Verify threshold settings are appropriate for the fault; Confirm actual voltage levels; Contact support if problem persists. |
